engine NISSAN MURANO 2003 1.G Repair Manual

To start your engine with a booster battery, the
instructions and precautions below must be
followed.
WARNING

If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.

Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.

Do not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.

Keep battery out of the reach of
children.
The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.

Whenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the battery
when jump starting.

Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.

Your vehicle has an automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.JUMP STARTING6-8

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. If the booster battery is in another vehicle,
position the two vehicles to bring their bat-
teries into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the selector leverto the P (Park) position. Switch off all unnec-
essary electrical systems (light, heater, air
conditioner, etc.).
3. Remove vent caps on the battery (if so
equipped). Cover the battery with an old
cloth as illustrated to reduce explosion haz-
ard.
4. Connect jumper cables in the sequence as
illustrated (
A
→
B
→
C
→
D).
CAUTION

Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (for example, strut mounting
bolt, etc. — not to the battery).

Make sure that cables do not touch
moving parts in the engine compart-
ment and that clamps do not contact
any other metal.
5. Start the engine of the other vehicle and let it
run for a few minutes.
6. Keep the engine speed of the other vehicle at
about 2,000 rpm, and start your engine in the
normal manner.
CAUTION
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying
again.

7. After starting your engine, carefully discon-
nect the negative cable and then the positive
cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover the
vent holes as it may be contaminated with
corrosive acid.Do not start the engine by pushing.
CAUTION

CVT models cannot be push started.
This may cause transmission dam-
age.

Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.

Never try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
WARNING

Do not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.

To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the ra-
diator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.

Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or if
you feel a lack of engine power, detect abnormal
noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the
parking brake and move the selector lever to
the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to maximum hot

and fan control to high speed.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no steam
or coolant can be seen before proceeding.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine.
WARNING

Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in the
cooling fan, or drive belt.
The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
6. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at the
nearest NISSAN dealer.When towing your vehicle, all State, provincial
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service
operators are generally familiar with the appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental damage
to your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advisable
to have the service operator carefully read the
following precautions.
WARNING

Never ride in a vehicle that is being
towed.

Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION

When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-
tion. If any unit is damaged, dolliesTOWING YOUR VEHICLE

Your new NISSAN has been designed to have
minimum maintenance requirements with longer
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your
NISSAN’s good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make sure that
scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
Scheduled maintenance:
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “Service and Mainte-
nance Guide”. You must refer to that guide to
ensure that necessary maintenance is performed
on your NISSAN at regular intervals.
General maintenance:
General maintenance includes those items
which should be checked during normal day-to-
day operation of the vehicle. They are essential if
your vehicle is to continue to operate properly. It
is your responsibility to perform these proce-
dures regularly as prescribed.Performing general maintenance checks require
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
your NISSAN dealer.
Where to go for service:
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and tuned by a NISSAN dealer.
NISSAN technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN
vehiclesbeforethey work on your vehicle,
rather than after they have worked on it.
You can be confident that your NISSAN dealer’s
service department performs the best job to
meet the maintenance requirements of your ve-
hicle — in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer check it promptly. In addi-
tion, you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMSAdditional information on the following
items with “*” is found later in this section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*:Check the pressure with a gauge at least
once a month and always prior to long distance
trips. If necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Wheel nuts*:When checking the tires, make
sure no nuts are missing, and check for any

loose nuts. Tighten if necessary.
Tire rotation*:Tires should be rotated every
7,500 miles (12,000 km). However, the timing
for tire rotation may vary according to your
driving habits and road surface conditions.
Wheel alignment and balance:If the vehicle
pulls to either side while driving on a straight and
level road, or if you detect uneven or abnormal
tire wear, there may be a need for wheel align-
ment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.
Windshield:Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified re-
pair facility.
Windshield wiper blades*:Check for cracks
or wear if they do not wipe properly.
Doors and engine hood:Check that all doors
and the engine hood operate smoothly. Also
make sure that all latches lock securely. Lubri-cate if necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*:Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Warning lights and chimes:Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield wiper and washer*:Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster:Check that the air
comes out of the defroster outlets properly and
in good quantity when operating the heater or air
conditioner.
Steering wheel:Check for changes in the
steering conditions, such as excessive free play,hard steering or strange noises.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks hold securely in all latched positions.
Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal does
not catch or require uneven effort. Keep the floor
mats away from the pedal.
Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Brake pedal and booster*:Check the pedal
for smooth operation and make sure it has the
proper distance under it when depressed fully.
Check the brake booster function. Be sure to
keep floor mats away from the pedal.
Parking brake*:Check that the lever has the
proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only the
parking brake is applied.

Continuously Variable Transmission (CVT)
P (Park) position mechanism:On a fairly
steep hill check that the vehicle is held securely
with the selector lever in the P (Park) position
without applying any brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel).
Windshield washer fluid*:Check that there is
adequate fluid in the tank.
Engine coolant level*:Check the coolant level
when the engine is cold.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, deterioration
or loose connections.
Brake fluid level*:Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Engine drive belts*:Make sure that no belt isfrayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level spot
and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Exhaust system:Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately locate the trouble
and correct it. (See “Precautions when starting
and driving” in the “5. Starting and driving”
section for exhaust gas (carbon monoxide).)
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see “Cleaning
exterior” in the “7. Appearance and care” sec-
tion.
Fluid leaks:Check under the vehicle for fuel,oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.8-4
Maintenance and do-it-yourself

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the selector
lever to the P (Park) position.

Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.

Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable be-
fore working near the fan.

If you must work with the engine
running, keep your hands, clothing,hair and tools away from moving
fans, belts and any other moving
parts.

It is advisable to secure or remove
any loose clothing and any jewelry,
such as rings, watches, etc. before
working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.

Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.

On gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, the fuel filter or fuel lines shouldbe serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is off.
CAUTION

Do not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.

Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.

Never leave the engine or the CVT
related component harness connec-
tor disconnected while the ignition
key is on.

Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
